TPA3118 - separate AVCC, PVCC supplies?

gmarsh
Prodigy 250 points

Hi,

Is it possible to run a lower voltage on AVCC than PVCC?

I'm trying to minimize quiescent power consumption as much as possible in a battery powered design. The 3118's datasheet's electrical characteristics page and example schematics show AVCC and PVCC connected together, but there's nothing specifically saying they have to be the same voltage.

Thanks!
